My invention relates to improvements in humidifiers, and the object of my improvement is to supply a very simple, inexpensive and effective device of this class, particularly designed for removable insertion through the cavities of ranged radiator loops.

Another object of my improvements is the provision of spacing members for a capillary sheet within a vessel of the device, adapted to support the sheet a distance above the bottom of the vessel to permit free circulation of a liquid under and about the sheet, whose body projects above the vessel within said cavity, and which means may keep thesheet evenly and thoroughly moistened throu h the action of capillary attraction while su jected to heat radiatedfrom the radiator coils adjacent thereto. 7 p

Another object of my improvements is to supply in combination with said vessel a supply tank therefor having a supply port thereinto at the bottom, and having a top overflow port in communication with the upper part of the vessel, governing the level of the liquid supply in the tank as also cooperating with the other port in the vessel supply, as an overflow into said vessel.

These objects I have successfully acc0mplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Fig. 1 is a front elevation of a conventional radiator of the looped type, with parts broken away, and showing associated therewith removably my improved humidifier device, the latter in medial vertical longitudinal section except certain parts which are in elevation. Fig. 2 is a top plan of my humidifier, and Fig. 3 is an enlarged vertical cross section of the vessel and its porous humiditying member, the upper part of which is broken away.

The conventional radiator shown in Fig. 1

has ranged loops or coils 1 with the usual top and bottom connections at 2 and 3. The inner cavity of the radiator or interspace of each coil is usually very narrow transversely.

The numeral 7 denotes an open top narrow and elongated vessel, whose dimensions are such as to permit it to be mounted removably in the narrow interspace of the coils lrestin upon the bottom-connections 3. At .one en of this vessel is an open top cylindrical tank 4, but which ma be otherwise shaped, and which is fastene to the end wall of the vessel, the contacting parts having at top and bottom registering ports 5 and 6 res ectively, the port 6 being a suppl port or said vessel when the tank is filled with water or other liquid. and the upper port 5 serving as an overflow port into the vessel, thus governing the level of the tank, the upper edges of both said vessel and tank beingpreferably although-not necessarily on one level.

The numeral 9 denotes a rectangular sheet of porous material appropriate-to receive and conduct a liquidtherethroughby capillary attraction, and its substance is rigid in order to hold its shape, therefore may be made from absorbent paper or the like. The lower margin of this sheet may have a U-shaped rigid binding 8 of metal or other material, and the binding 8 may have longitudinally spaced depending legs or supports 10 to rest upon the bottom of the vessel 7 to keep the sheet thereabove in allowing free circulation-of liquid below the sheet and at each side thereof within the vessel, as shown in said Fig. 3. This free circulation is necessary, because if the sheet is permitted to rest with its lower edge upon the bottom of the vessel, and as the sheet when soaked through its lower part where immersed tends to swell, especially when made of wood or other vegetable fibers, the 4 narrow interspace of the vessel becomes closed at the sides as well as at the bottom, so that the sheet is but partially wet, and its upwardly projecting body part receives too little liquid by capillary attraction for humiditying urposes. In my invention, the troughed bin ing 8 keeps the lower margin of the sheet 9 from widening when wet, and the props or legs 10 keep the sheet spaced for free passage of liquid and even wetting thereof. The

sheet 9 thus is maintained moist, and the radiator heat vaporizes the liquid therein for atmospheric diffusion. I

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

A humidifier, comprising an open top narrow elongated vessel, an open tank at one end thereof having communication therewith at top and bottom only as supply and overflow means respectively, a porous sheet positioned in said vessel to extend thereabove, and a binder along the lower edge of said sheet with depending longitudinally spaced projections to serve as rigid reinforcing means for the lower part of the sheet while spacing it above the bottom of the vessel and from opposite side walls thereof, the sheet being adapted to convey a liquid by capillary attraction throughout its entire substance, and the narrow vessel being removably seated within the coils of a radiator.

Intestimony whereof aflix my signature.
